Childhood Cancer Data Initiative (CCDI): A Cohort of Hispanic Children with Acute Lymphoblastic Leukemia; Bloom Syndrome in a Mexican American Family with Rhabdomyosarcoma

Retrospective case-control genetic study of Hispanic children with acute lymphoblastic leukemia (ALL) treated 1994-2013, comparing 14 treatment-related pancreatitis (TRP) cases to 46 treatment-matched controls without pancreatitis. Targeted sequencing of 23 genes (pancreatitis-related and asparagine-metabolism genes) was performed from post-remission blood DNA; select HLA types were inferred from whole-exome data in cases. CFTR and ASNS variants were enriched in TRP (notably CFTR V470M, OR 4.27, p=0.025).
